I would try the local vets, bellbrae and there are a few near global pet foods. The most likely place would be sunset point as thats where we all walk our dogs. I'll keep a look out and take riley on a big walk around the area, he's a dog magnet. To be honest the local humane society are not very dynamic. If you want posters put up then drop me an email I'm on the dog walk paths daily.
